My research concerns the development of mathematical abilities and mathematics anxiety, and the contribution of reasoning skills to mathematics performance. I am also interested in how affective and motivational states influence maths and reasoning abilities, as well as people’s decisions, and how maths and reasoning skills can be improved by training. I also have a background in the development of reasoning skills in typical development and in special populations (in developmental dyscalculia and autism). I am particularly interested in reasoning heuristics, probabilistic reasoning and analogical reasoning. I also work on projects related to psychological measurement. My work has been funded by grants from the ESRC, the Nuffield Foundation, the Royal Society, the British Academy, and the Higher Education Academy Psychology Network. As a student, I received study visit grants from the Experimental Psychology Society and the Action Austria-Hungary Fund. I also received an outstanding student paper award from the Cognitive Science Society.
